Other » Blowing 28w 2D's

Hello,

We have issues on one of the apartment blocks that we look after. Long story short we have 12 lights per block. All 28watt 2D's. We are changing ballasts and lamps weekly at the moment. It is not a fixed wiring issue as the install is brand new (by us) and new C.U. We are feeding the circuit with a C10. The lights are switched via ceiling sensors. We have been in touch with Thorn who have been very good but the lamps are still not lasting anywhere near as long as they should. If we have to change the fittings then we are prepared to do it but we have fitted these lights before without these kind of problems. Any ideas greatly appreciated as always. Yours from a very tired, over hungry and ballasted out Dave. Roll on the chinese!

please help

Thanks !

I didn't find the right solution from the internet.
